Ongoing research and more
We consider quantum transport in different types of superconducting heterostructures. Our research interest is focused on spectral characteristics and heat transport in these structures. Our work is being done in the framework of equilibrium and non-equilibrium Green’s function approach, which is very useful for describing different physical properties of the system as the local density of states and Josephson current.
